Abstract: Network perspective has already been applied in diverse area comprehensively. However, the innovation network of agriculture might have been neglected. This paper, using co-publication and co-patent in the field of agriculture in Shanghai from 1988 to 2015 as the original data, focuses on understanding the structural and spatial characteristics of the innovation network. There are some conclusions drawn from the research. Firstly，The innovation network obviously has core-periphery paradigm. Secondly， From the spatial characteristics of the network, although other cities like Beijing, having become powerful knowledge pool, the actors still tend to cooperate with the partners which located within Shanghai. Thirdly, the research institutions has become the center of science network, while the structure of technology network is on the initial stage and display as a chain. The results provide a new research perspective on the evolution of innovation network, which has some guided and reference meaning to the agricultural innovation system.
